    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application is a continuation of prior, co-pending Application Ser. No. 12/706,268, entitled “Trauma Nail Accumulator,” filed Feb. 16, 2010, which claims priority to and benefit of U.S. U.S. Provisional Application No. 61/152,866, filed on Feb. 16, 2009, the disclosures of which are all hereby expressly incorporated by reference herein in their entirety.
    • FIELD
  • Embodiments of the present invention relate, in general, to an accumulator device, and, in particular, to an accumulator that may store energy within an inflatable intramedullary rod.
    • BACKGROUND
  • To stabilize a bone fracture using an inflatable device, such as an inflatable intramedullary nail, the inflatable device may have to maintain a certain pressure for an extended period of time, which may include the duration of implantation. If such a pressure is not maintained, the bone fracture may not heal or it may malunion. Many things may affect the pressure in this closed system, which may include the inflatable nail and fracture cavity. For example, after a fracture is set and the inflatable device is sealed off during implantation, any expansion of the intramedullary canal or leakage from the device may cause the system pressure to drop. In another example, even slight expansion of an inflatable balloon nail or small losses of fluid at joints or bonds may influence the system pressure. If a system having no stored energy incurs such pressure losses, the pressure may drop immediately.
  • Thus, it may be advantageous to provide stored energy in an accumulator, which may supply energy, absorb pressure spikes, and stabilize a system during changes in fluid or cavity volume. The use of an accumulator may result in a system that is able to withstand greater volume losses or changes with a reduced effect on the system pressure. Such an accumulator may be located inside or outside an inflatable nail.

    •  DETAILED DESCRIPTION
  • Versions of the present invention comprise an accumulator device that stores energy that may be released to help stabilize and maintain a system pressure. In one embodiment, the accumulator device may be located within an inflatable device, such that the pressure in a bone fracture cavity may be maintained. In another embodiment, the accumulator device may be attached externally to an inflatable device after implantation of the device. In still another embodiment, the inflatable device may be an intramedullary nail. A further embodiment involves an accumulator device comprising a piston. Such a piston accumulator may comprise a spring or compressed air as its energy source. Another embodiment involves an accumulator device comprising a pressurized bladder. In another embodiment, the lumen of the inflatable device may be flexible.
  • Referring to FIG. 1, one example of an inflatable device 100 is shown. The inflatable device 100 may be of any suitable configuration as will be apparent to one of ordinary skill in the art. For example, inflatable device 100 may be an inflatable nail. In another example, inflatable device 100 may be an inflatable intramedullary nail. In still another example, inflatable device 100 may be of a type disclosed in Goldin et al. (US 2007/0123877, published May 31, 2007). Referring to FIG. 2, another version of an inflatable device 100 is shown. As displayed in FIG. 2, inflatable device 100 may be an inflatable nail. An inflatable device 100 may comprise, for example, a nail shaft 200, a proximal balloon 202, a distal balloon 204, and a nail tip 206. Inflatable device 100 may also comprise an accumulator 208. Accumulator 208 may be internal or external to an inflatable device 100. For example, FIG. 2 shows an internal accumulator 208.
  • Referring to FIG. 3, one example of an accumulator 208 is shown. In this example, accumulator 208 is located within an inflatable device 100. Specifically, FIG. 3 shows accumulator 208 located within a nail shaft 200. Accumulator 208 may comprise any number of parts as will be apparent to one of ordinary skill in the art. For example, the internal accumulator 208 shown in FIG. 3 comprises a piston 302. In the alternative, internal accumulator 208 may comprise a pressurized bladder (not pictured in FIG. 3). Accumulator 208 may also comprise an energy source 304. Energy source 304 may be any source capable of being compressed as will be apparent to one of ordinary skill in the art. For example, energy source 304 may be a spring or compressed air. An accumulator 208 may be mechanical or hydro-pneumatic, depending on the energy source 304. For example, a mechanical accumulator 208 may comprise a piston 302 that compresses a spring 304 to provide energy to the system. In another example, a hydro-pneumatic accumulator 208 may comprise a piston 302 that compresses air 304 to provide energy to the system. Accumulator 208 may also comprise an orifice 306. Orifice 306 may comprise any suitable means to adjust the fluid flow in accumulator 208. For example, orifice 306 may be an adjustable valve. In another example, as shown in FIG. 3, orifice 306 may be a coupler located between nail shaft 200 and the body of accumulator 208. A seal 308 may seal piston 302 from a fluid leak. For example, seal 308 may prevent fluid used to inflate distal balloon 204 from leaking into energy source 304. Seal 308 may be produced by any suitable means as will be apparent to one of ordinary skill in the art. For example, an o-ring may comprise seal 308.
  • Referring to FIG. 4, another example of an internal accumulator 208 is shown. In this example, accumulator 208 comprises a piston 302 and a spring 304. An accumulator 208 may compensate for a change in system volume or pressure to help maintain a stable pressurized system. For example, a piston 302 may translate within a nail shaft 200, remaining in contact with spring 304. In this way, when a system is pressurized, piston 302 may exert a force on energy source 304, causing it to compress. For example, after insertion of an inflatable device 100 and inflation of a balloon 202 or 204, piston 302, which may be exposed to the internal hydraulic pressure of device 100 via orifice 306, may compress energy source 304, which stores energy. A piston 302 may compress energy source 304 until the pressure of the energy source 304 and the system pressure equalize or until energy source 304 is fully compressed. While inflatable device 100 is implanted or otherwise in use, accumulator 208 may compensate for losses or changes in the pressure or volume of the system to maintain a stable pressure in the system. For example, accumulator 208 may stabilize pressure or volume by supplying fluid to the closed system. In another example, a change in system pressure may cause the fluid pressure exerted on piston 302 to lessen, which may simultaneously lessen the compression force piston 302 exerts on energy source 304. In this way, energy source 304 may extend or expand to take up the space of the lost fluid, and therefore minimize system pressure loss. In another embodiment (not pictured), an internal accumulator may comprise two separate chambers, and therefore two pistons and two orifices. Such an accumulator may have a single spring, which equalizes the system pressure between each chamber.
  • In another embodiment, an accumulator may be external to an inflatable device 100. Referring to FIG. 5, such an inflatable device 100 and an external accumulator 500 is shown. In FIG. 5, the inflatable device 100 is a nail having a shaft 200, a proximal balloon 202, and a distal balloon 204. Rather than being located within the inflatable nail 100, accumulator 500 may be located outside the nail 100. Referring to FIG. 6, another example of an external accumulator 500 is shown. In this example, accumulator 500 comprises an orifice 502, an energy source 504, a piston 506, and a seal 508. An orifice 502 may comprise any suitable means to adjust the fluid flow in the accumulator 500. For example, orifice 502 may be an adjustable valve. In another example, as shown in FIG. 6, orifice 502 may be a coupler located between nail shaft 200 and the body of accumulator 500. Energy source 504 may be any source capable of being compressed as will be apparent to one of ordinary skill in the art. For example, energy source 504 may be a spring or compressed air. An external accumulator 500 may be mechanical or hydro-pneumatic, depending on the energy source 504. For example, a mechanical accumulator 500 may comprise a piston 506 that compresses a spring 504 to provide energy to the system. In another example, a hydro-pneumatic accumulator 500 may comprise a piston 506 that compresses air 504 to provide energy to the system. A seal 508 may seal piston 506 from a fluid leak. For example, seal 508 may prevent fluid used to inflate distal balloon 204 from leaking into energy source 504. Seal 508 may be produced by any suitable means as will be apparent to one of ordinary skill in the art. For example, an o-ring may comprise seal 508.
  • External accumulator 500 may compensate for a change in system volume or pressure in a similar manner as internal accumulator 208. For example, piston 506 may translate within a separate housing 600, remaining in contact with energy source 504, which in this example is a spring. In this way, when a system is pressurized, piston 506 may exert a force on energy source 504, causing it to compress. For example, after insertion of an inflatable device 100 and inflation of a balloon 202 or 204, piston 506, which may be exposed to the internal hydraulic pressure of device 100 via orifice 502, may compress energy source 504. Piston 506 may compress energy source 504 until the pressure of the energy source 504 and the system pressure equalize or until energy source 504 is fully compressed. While inflatable device 100 is implanted or otherwise in use, accumulator 500 may compensate for losses or changes in the pressure or volume of the system to maintain a stable pressure in the system. For example, accumulator 500 may stabilize pressure or volume by supplying fluid to the closed system. In another example, a change in system pressure may cause the fluid pressure exerted on piston 506 to lessen, which may simultaneously lessen the compression force piston 506 exerts on energy source 504. In this way, energy source 504 may extend or expand to take up the space of the lost fluid, and therefore minimize system pressure loss. In another embodiment (not pictured), an external accumulator may comprise two separate chambers, and therefore two pistons and two orifices. Such an accumulator may have a single spring, which equalizes the system pressure between each chamber.
  • In an alternative embodiment, an accumulator may comprise a pressurized bladder instead of a piston. Referring to FIG. 7, a bladder accumulator 700 is shown. Bladder accumulator 700 may be internal or external to an inflatable device 100. In FIG. 7, bladder accumulator 700 is shown external to inflatable device 100. In this embodiment, inflatable device 100 may be an inflatable nail, as shown in FIG. 7. Inflatable device 100 may comprise, for example, a nail shaft 200, a proximal balloon 202, and a distal balloon 204. Referring to FIG. 8, an external bladder accumulator 700 is shown with another inflatable device 100. In this example, inflatable device 100 is a single lumen nail. The single lumen nail may have a nail shaft 800.
  • Referring to FIG. 9, another example of a bladder accumulator 700 is shown. Bladder accumulator 700 may comprise, for example, an orifice 702, an energy source 900, and a bladder 902. Orifice 702 may comprise any suitable means to adjust the fluid flow in accumulator 700. For example, orifice 702 may be an adjustable valve. In another example, as shown in FIGS. 7-8, orifice 702 may be a coupler located between nail shaft 200 and/or 800 and the body of accumulator 700. Energy source 900 may be comprised of a pressurized or compressed gas within a bladder 902. The compressed gas may be, for example, nitrogen. Bladder accumulator 700 may also compensate for a change in system volume or pressure. In a bladder accumulator 700, the fluid used to inflate an inflatable device 100 may exert a force against an energy source 900, compressing the gas within bladder 902 and pressurizing it further. If the system loses pressure, the pressurized bladder 902 may expand, take up the room of the lost fluid, and thereby maintain the system pressure.
  • Referring to FIG. 10, another embodiment of an accumulator device is shown. In this embodiment, inflatable device 100 may comprise an inflatable nail and a flexible lumen. Such a flexible lumen may, for example, ease the implantation of the inflatable nail. In the figure, the flexible lumen inflatable device 100 includes an internal accumulator 208. A flexible lumen inflatable device 100, however, may be used in conjunction with any of the other embodiments described in this application as will be apparent to one of ordinary skill in the art. For example, a flexible lumen inflatable device 100 may be combined with an external accumulator, an internal or external piston accumulator, and/or an internal or external bladder accumulator.
  • The versions presented in this disclosure are examples. Those skilled in the art can develop modifications and variants that do not depart from the spirit and scope of the accumulator device.
